Invoke runbook every minute

Question

This may possibly be a stupid question but I'm going to ask anyway ;-)
We have created a runbook to provision users in Lync, and this runbook goes every minute. I have the box ticked for wait for completion on the invoke runbook activity.
On enabling a handful of users the process is very quick, but we're getting to a point in our lync deployment that we are adding sometimes over 100 users at a time. I'm seeing some errors that I can't really correlate with anything else, so my question is
this.
If a runbook runs every minute, and the data it's working on takes more than a minute to complete, will the runbook religiously spawn every minute and perhaps trample on work of a previous runbook?

Answer 1

Ryan,
I've double-checked my runbook and have that set, and yet I'm seeing what appears to be the runbook running multiple times. As it runs every minute, under the Log tab I saw several instances with a status of running.
My runbook is actually two, the first has the every minute schedule, and the invoke runbook activity that passes data over to the second part of the runbook that actually does the work. This worker runbook has an init data activity, and then three script
activities that carry out the work of getting a list of users from AD that meet the provisioning criteria, then enable a given user, and finally clear out the provisioning criteria.
On the invoke runbook activity, I also have set wait for completion to be true. If what I'm seeing is normal then cool, otherwise i'm inclined to put in some sort of check just to make sure.
